M&W Precast and Construction Supply has made precast concrete products and supplied construction materials for Pennsylvania and the surrounding region since Woodrow Wehrung began manufacturing septic tanks in 1950. Now in its third generation under Jason Wehrung, the company produces custom precast structures and concrete tanks while also supporting contractors with drainage and construction supplies. Its history includes a 1957 patent for integrated concrete tank baffles and a 2013 transition to the M&W name.
